### Description

Detailed nuclear-structure calculations were made to predict the rate of the M1 excitation of $^{125}$Te from the 1/2$^+$ ground state to the first excited 3/2$^+$ state at 35.5-keV, by the collision with WIMPs in our galactic halo. A complete calculation of the relevant spin structure was performed in the framework of the shell model. The valance space included the orbits: 1g$_{7/2}$, 2d$_{5/2}$, 1h$_{11/2}$, 3s$_{1/2}$, and 2d$_{3/2}$. There will be 43 kg of $^{125}$Te in the present version of CUORE, and the predicted rate is very interesting. In fact the predicted rate is significantly faster than that estimated in 1988 by Ellis, Flores and Lewin, although our calculation of the rate in $^{83}$Kr was similar to their estimate. The predicted rate in $^{125}$Te as well as a brief discussion of the principles of operation of the CUORE detector will be given.
